CGI Window Replacement: The Hialeah Owner’s Guide
If your CGI window has a failed seal, cracked glass, or a frame that won’t close square, we stock and install CGI-compatible replacement windows throughout Hialeah, typically between $450 and $1,200 per window installed depending on size and series. Most CGI window replacements in Hialeah are completed same-day once we confirm the model and measurements, and we carry common CGI sashes, glass packs, and hardware on our trucks. You’ll usually discover the problem the way most Hialeah homeowners do: a window that suddenly fogs between the panes, a crank that grinds, or water showing up on the sill after one of our summer downpours.

Which CGI Models This Applies To
CGI windows are built for South Florida’s wind and impact codes, and we replace parts across their main residential lines: the Estate Collection, the Sentinel series, and the Targa series, plus older CGI models still common in Hialeah’s 1980s and 1990s concrete-block homes. The fastest way to identify your window is to look for the CGI label etched into the glass corner or on the frame edge, which lists the model and production date. If the label is gone, we measure the glass thickness and frame profile on-site. For CGI specifically, we recommend OEM glass packs when the window is still under manufacturer warranty, because CGI’s laminated glass and interlayer ratings are engineered to their frames and going aftermarket can void that warranty. For out-of-warranty windows, we offer quality aftermarket glass packs that match CGI’s thickness and impact ratings at a lower price, and we’ll tell you plainly which route makes sense before you spend a dollar.
Signs Your CGI Window Replacement Is Failing
- Fogging or condensation between the panes. The seal has failed and the argon or krypton gas fill is gone. This is the most common CGI failure in Hialeah’s heat and humidity, and it means the insulated glass unit needs replacement, not the whole frame.
- Water on the interior sill after heavy rain. The weatherstripping or frame seal is compromised, often because years of sun exposure have hardened the rubber and created gaps at the corners.
- Visible cracks or chips in the glass. Even a small impact crack weakens the laminate and compromises the impact rating. If you can feel the crack with a fingernail, it’s spreading.
- Difficulty cranking, locking, or sliding the window. Hardware wears out before glass does in coastal air. Salt and humidity corrode the pivot points and roller assemblies, especially on older CGI single-hung and casement windows.
- You can feel drafts or hear street noise more than before. The frame-to-sash seal has degraded, and with Hialeah’s afternoon storms and traffic noise on Palm Avenue and 49th Street, you’ll notice it quickly.
Replacement Cost & What’s Included
In Hialeah, a full CGI window replacement runs $450 to $1,200 installed, with single-hung units on the lower end and larger fixed or casement windows on the higher end. Glass-pack-only replacements are typically $250 to $500. The range depends on glass size, whether we’re matching an existing CGI frame or replacing the entire window unit, and whether the window is standard or custom-shaped. Our quote includes the part, labor, haul-away of the old unit, and sealing with materials rated for South Florida exposure. You’ll get the price in writing before any work starts, and it won’t change once we begin unless we find hidden damage we show you and you approve in advance. Every replacement carries the Winslow Done Right Promise: if it’s not done right, Ed Winslow makes it right. At Winslow Windows & Doors, my name’s on the truck and on the warranty, and that’s not something Ed takes lightly.

DIY or Call Us?
You can safely check the label on your window, measure the glass opening, and note whether the failure is fogging, cracking, or hardware. What you shouldn’t attempt is removing a CGI impact window yourself. These units are heavy, and the laminated glass and frame systems are under tension when installed; a wrong move can damage the frame or drop a 40-pound sash. We’ve also seen Hialeah homeowners try to replace just the glass and end up with a unit that no longer meets Miami-Dade impact code because the sealant or anchoring wasn’t done correctly. If the window is fogged, cracked, or leaking, call (850) 998-3090 and we’ll send a tech to confirm what’s wrong and quote the fix. The estimate is free, and there’s no trip charge inside Hialeah.

FAQs
CGI windows typically last 20 to 30 years in Hialeah’s climate, though sealed glass packs often fail at the 10 to 15 year mark due to constant heat, humidity, and UV exposure. Hardware wears faster near the coast. If your windows are over 15 years old and showing symptoms, a replacement glass pack or sash usually restores performance without replacing the entire frame.
Glass fogging, seal failure, and broken hardware can often be repaired by replacing the glass pack, weatherstripping, or hardware assembly rather than the whole window. Cracked glass and frame rot usually require full replacement. We’ll tell you which applies to your window before quoting anything. Call (850) 998-3090 for an exact diagnosis and free estimate.
Most single-window replacements in Hialeah are done in 2 to 4 hours, including removal of the old sash or glass pack, installation, sealing, and cleanup. Multi-window projects may take a full day or two depending on access and framing condition. We’ll give you a time window when we quote the job.
We stock common CGI glass packs, sashes, weatherstripping, and hardware on our trucks and in our local inventory.
